  Design Note
  1000V Output, No-Opto Isolated Flyback Converter
  George Qian, Michael Wu
  Introduction
  Isolated flyback converters are used in automotive,
  industrial, medical and telecom applications where the
  power supply must be reliable, easy-to-use, high voltage
  and isolated, and must provide excellent regulation over
  load, line and temperature. LTВ®8304-1 is an isolated noopto flyback converter specially optimized for high output
  voltage applications—providing outputs up to 1000V.
  Traditionally, the regulation feedback loop requires a bulky
  high voltage divider to directly sense the high output
  voltage, along with opto-couplers to convey feedback
  information back through the isolation barrier. The bulky
  resistor solution results because a 1206 resistor can handle
  200V maximum. So to sense 1000V, at least six 1206
  resistors are required, plus a small bottom resistor. 1000V/15mA Output, from a 4V–28V Input
  An LT8304-1 flyback converter design features a low
  component count. Figure 1 shows a complete 4V–28V
